Hello all,
I'm curious what kind of varnish stats everyone here has recorded and what
the "maximum" uptime you have with varnish not restarting itself. I'm
trying to track down a nasty memory leak I believe exists in varnish which
you can see for yourself in "top". It appears varnishs memory just
increases infinitely until it crashes and restarts itself. Under a good
amount of traffic (20 Mbit/s out) I can't seem to get varnish to stay up
more than 5 hours without the memory leak kicking its ass-- however, here
are the stats from a varnish server that's only pushing out about
5-9Mbit/s. Please share your stats and information that relates to this
possible leak that we have going so we can track this sucker down!
